Abstract This study aimed to investigate the possibility of increasing the germination traits and early growth characteristics of Mediterranean cypress by applying nanopriming and magnetic field. To perform nanopriming, seeds were primed with nanochitin, nanochitosan and nanocellulose at a concentration of 1% for 2 h. For magnetopriming, the seeds were exposed to a magnetic field at three levels (20, 30 and 40 mT) for 1, 10 and 20 min and then sown. In combined treatment, the seeds were exposed to the magnetic field and then primed in nanoparticle solutions at the same treatments as mentioned earlier, and were planted. Non-exposed seeds were used as a control. The selected seed germination parameters (the percentage and speed of germination, stem and radicle length, collar root diameter, fresh and dry weights of the radicle and stem, number of leaves and leaf area) of young seedlings were examined. The interaction of nano × magnetic resulted in significant differences in the number of leaves, leaf area, length of the radicle, length of the stem, fresh weight of the radicle, fresh weight of the stem and stem dry weight traits. The results showed that among all the applied treatments, 10 min magnetism to 20 mT and then priming with 1% solution of nanocellulose was the best. It increased the germination percentage (1.31 times), germination rate (1.46 times), number of leaves (1.57 times), leaf area (1.36 times) and radicle length (1.74 times) compared to the control (no treatment). A 20-min treatment under a 30-mT magnetic field (without nanoprime) is also recommended.

Abstract The agroforestry system provides important economic and ecological benefits for local communities, one of which is obtained from the application of planting patterns and plants species in it. This research aims to explain the planting pattern of rubber agroforestry developed by the community in Menggala Mas Village, Lampung Province, Indonesia. The approach in this research is qualitative. Data collection methods included observation, in-depth interviews, and documentation studies. The planting patterns of agroforestry system on their rubber plants were analysed. The research results showed that there are three agroforestry planting patterns implemented by the community, namely, alley cropping, trees along border and random mixture. The dominant combinations in alley cropping were rubber/karet (Hevea brasiliensis) – pulai (Alstonia scholaris) and rubber–mentru (Schima wallichii) – kayu afrika (Maesopsis eminii). The dominant combinations in trees along border were rubber–akasia (Acacia auriculiformis), rubber–jackfruit (Artocarpus heterophyllus) – cempedak (Artocarpus integer) and rubber–petai (Parkia speciosa) – jati (Tectona grandis). The dominant combinations in the random mixture were rubber–jengkol (Pithecellobium lobatum), rubber–petai–jengkol–akasia, rubber–jackfruit–cempedak, rubber–pulai–mengkudu (Morinda citrifolia L.) – jengkol and rubber–banana (Musa paradisiaca) – gadung (Dioscorea hispida) – sungkai (Peronema canescens Jack). Forty-one plant species were found. The local community wants to develop this planting pattern because the rubber agroforestry planting pattern can provide direct and indirect benefits such as a greater variety of plants which can increase their income; also, the products can be sold or consumed by the family, as a fence, fire break or barrier to other farmers’ land, can provide shade to reduce hot temperatures when farmers are working, and can reduce the risk of flooding and soil erosion to support soil and water conservation within the ‘Omou’ (garden/forest). The government and agricultural extension workers need to carry out regular guidance and outreach programmes regarding rubber agroforestry development strategies to increase public knowledge.

Abstract Knowledge about changes occurring in the genetic structure of populations is extremely important in the case of endangered species. Research studies conducted in space and time allow us to identify factors that are influencing gene flow. Especially in the case of species occurring in the form of dispersed, more or less isolated populations, this is crucial for developing effective conservation strategies. The Carpathians are one of the most important capercaillies stronghold in Central Europe. The population here is fragmented, and at least, some groups of birds are small and isolated. This study aimed to determine whether the genetic structure of the capercaillie in the Polish part of the Carpathians has changed over the last decade. The research was conducted in three Polish national parks: Babia Góra National Park (BAB), Gorce (GOR) and Tatra (TAT). A total of over 1,300 non-invasive samples were collected for genetic analyses in two periods: 2010–2013 and 2021–2022. Individuals were identified using microsatellite markers. It was found that during the research period, there were approximately 200 capercaillie individuals in the Parks. The level of genetic variability in individual strongholds has not changed significantly. However, traces of a new gene pool were found in BAB, which could have appeared from other areas of the Carpathians where the species is being reintroduced. GOR shows features of a sink population: low genetic variability, low number of individuals and gradual decline in emigration. During the period covered by the study, the genetic structure has changed little: the studied strongholds are partially genetically isolated, but gene flow between BAB and GOR appears to be increasingly limited. TAT is a hybrid and transition zone for gene flow between smaller strongholds. The results emphasize the importance of areas with stable, numerous populations for the survival of smaller, peripheral groups of the capercaillie in mountain areas.

Abstract The article presents the results of a lichenological inventory carried out in the “Tabórz Pine” nature reserve, which protects a unique old-growth forest dominated by Scots pine and European beech. The aim of the research was to document the taxonomic and ecological diversity of the lichen biota in the reserve and, on this basis, determine the role and importance of this site as a refuge for stenoecious forest lichens. In an area of 95.32 ha, 118 species of lichens were found, including 43 species included in the Polish national Red List along with 17 species having the status of lowland old-growth forests in Poland. These values allow the reserve to be included in the group of important forest lichen refuges in north-eastern Poland. The obtained results also prove that mixing tree species with complementary ecological features can modify the functioning of the forest not only in terms of its economic features, but also its ecological role in shaping and protecting the species diversity of forest lichens.

Abstract In Jammu and Kashmir's Govindpora (Ramban) and Salamabad (Baramulla), horticultural nurseries with a majority of Olea europaea subsp. cuspidata (Wall. & G.Don) Cif. plantings were examined for possible bark beetle attacks. These olive tree plantations are infested with a variety of insect pests, but the bark beetle Hylesinus macmahoni (Stebbing, 1909) did significant harm to the olive trees that carry fruit. The beetle attacks and consumes the phloem tissues of the plant during its development, causing the afflicted trees to become weak and eventually die. At both sites, infestations of H. macmahoni were discovered. The cytochrome oxidase subunit I (COI) gene was used to validate the species' diagnosis, and its morphological characteristics were re-described. The species has a polygynous matting system (one male and two females), producing two full and a third partial generation annually in Kashmir.

Abstract In Poland, the tree improvement programme was initiated in 2004, but the trials for European larch (Larix decidua Mill.) did not start until 2021. Our aim is to present certain aspects of the methodological approach of progeny testing for this species. The European larch, known for its rapid growth among native coniferous trees in Europe, holds great promise for forest breeding. Unfortunately, its natural range in Poland is limited, with rare but well-known valuable provenances. In 2023, six progeny tests were established using the same 130 open-pollinated families, derived from plus trees originating from valuable seed regions (Md51, Md61, Md71) and areas below 52° N latitude. After a decade of growth, the results will be used to identify valuable genotypes and establish advanced-generation seed orchards.

Abstract Black locust (Robinia pseudoacacia L.) was introduced in Poland over 200 years ago, and its distribution area now covers the whole country, with the highest concentration of occurrence in the western part. Breeding of this species has been started in Poland for about 20 years, albeit on a limited scale, and two selected seed stands, 34 plus trees and two seed orchards have been registered. So far, selection efforts have not been coupled with the recognition of variation in the genetic structure of local populations. To fill the knowledge gap on genetic diversity, we selected the seven qualitatively best populations of R. pseudoacacia for our study. To clarify the origin of the Polish population of R. pseudoacacia, a sample from a seed stand in eastern Germany and from a seed orchard with Hungarian clones from the Oborniki Śląskie Forest District was added. In this study, three microsatellites were used to evaluate genotypes: Rops15, Rops16 and Rops18, with the Rops15 locus (motif AG) showing hypermutability. Moderate or high variability was observed in all microsatellite loci examined, with a total of 27 alleles identified. In all stands, the average observed number of alleles per locus was higher than the average effective number of alleles per locus. Three main clusters have been identified in the genetic structure of the population, one of which is represented by the population from the Regional Directorate of State Forests in Zielona Góra. The second group comprised the populations from Mieszkowice, the populations Pińczów and Wołów, and the population from Germany. The last one included population from Strzelce and Oborniki Śląskie, where the population from Hungary is represented. This may be of great importance for practice. Perhaps it is worth postulating the separation of two seed regions. Under most scenarios, climate change is projected to change the distribution of forest types and tree species in all biomes. It can be assumed that the importance of black locust in times of climate change is likely to increase.

Abstract Firebreaks are one of the protective measures used to safeguard forests in case of fire. Their purpose is to limit the possibility of fire spreading. This article describes how these protective measures are implemented along public roads in selected European countries. Based on the information gathered, it was found that there is a wide variety of approaches to firebreaks’ construction, mostly due to different climatic and geomorphological conditions that influence the overall risk of forest fires. The forms of firebreaks used in Europe along public roads are either a mineralised belt (without vegetation) or a cleared belt of materials that are particularly susceptible to ignition and fire spread. Methods combining both are also used. In Poland, there is a Type A belt, that is, a 30-m-wide belt at the border of a roadway or a facility that is free of dead trees, lying branches and felled or broken trees. In the absence of pan-European rules on preventive measures to protect forests from road fires, it might be helpful to establish a set of best practices that could assist in the revision of guidelines in individual countries.

Abstract The study presents an innovative, proprietary concept of identifying soft skills predisposing individuals to occupy a forestry position, along with the definition and discussion of key factors constituting the assessment criteria. The authors provide their individual perspective on the specific personality traits and attitudes relevant to the assessment of an employee's soft skills concerning their suitability for the given position. Six fundamental categories of skills and attitudes within the realm of soft skills for foresters were identified and proposed for evaluation. These categories included the following: Collaboration and information flow management: This category assessed the ability to effectively collaborate with other company employees and the sense of responsibility for achieving the team's goals. Special attention was paid to how information was communicated, facilitating planning, making changes and executing task effectively. Initiative and engagement: This category focused on the ability and willingness to seek and implement new solutions. It identified and proposed an assessment system for actions such as the forester's submission of new ideas and solutions to emerging problems, their engagement and identification with the company, their drive to improve existing work methods, and their adaptability to new tasks and working conditions resulting from changes. Shaping a positive company image: This category involved evaluating the attitude that leads to dignified and ethical representation of the company through appropriate appearance, behaviour and attitude. It encompassed aspects such as building strong relationships with customers, business partners and the company's environment, making agreements aligned with the company's interests and taking active steps to enhance the positive image of the forestry operation. Collaboration with external entities: This category analysed constructive actions defined as the interaction of the forestry district with external entities aimed at creating a favourable business climate for forestry operations. Independence and decision-making: In this category, competencies for independently managing the Forest District were discussed, without the need for direct supervision. The proposed assessment system considered the traits predisposing the forester to make quick and accurate decisions, anticipate their consequences, take personal responsibility for task execution and accept the consequences of their own or their team's work results. Developing subordinates: The final category analysed teamwork skills, with a particular focus on actions aimed at the systematic development of subordinates, recognising potential, and identifying areas for improvement and providing subordinates with opportunities to gain experience and enhance their qualifications and professional competencies. The assessment of the forester's soft skills in each category was based on a descriptive classification of their behaviour, which was assigned to five groups: unacceptable, below expectations, good, very good and outstanding. An illustrative description of employee behaviour facilitating their classification into one of these groups was developed for each evaluation category. The research results are presented in a Table 1, which shows the identified traits, the system for their identification (specified behaviours subject to assessment) and the assessment system. A rating system based on descriptive indicators was proposed to facilitate a homogeneous and repeatable employee assessment process, which is one of the fundamental elements of human resource management. In today's world, the concept of sustainable development is being replaced by efforts to sustain the system through its regeneration at the economic, social and sociological levels. Therefore, the presented concept of identifying and evaluating soft skills was compared with the principles of management in the Volatility, Uncertainty, Complexity, Ambiguity (VUCA) environment.

Abstract Trees happen to be a prominent source of nutritive fodders and provide sufficient nutrients to the cattle throughout the year. The leaves of two Bauhinia species, that is, Bauhinia retusa and Bauhinia variegata, were collected in different seasons from their natural growing habitats. The collected leaves were air-dried to make a fine powder, and the nutrient concentrations were estimated as per the standard processes. Significant variations were recorded in the nutritive values of both species in different seasons. The leaves of B. retusa revealed highest dry matter and total carbohydrate in the summer season, while the rainy season exhibited the highest value of ash per cent and crude protein.The ether extract and nitrogen-free extract per cent were higher in the winter season, and the maximum crude fibre and organic matter per cent were prominent in the spring season. In case of B. variegata leaves, the dry matter, nitrogen-free extract, ash and ether extract per cent were higher in the winter season. The highest crude fibre percent and total carbohydrate were found to be the maximum in the rainy season, and crude protein was higher in summer season. The results of the present study revealed that the both Bauhinia species are good sources of green fodder for cattle, especially in the rainy season in case of B. retusa and in the summer season for B. variegata, to correct the deficiency of protein in animals in the hill state of Uttarakhand, India.
